[jboss-jira] [JBoss JIRA] (WFLY-980) Failure when using queueless-thread-pool as the pool for a web connector

Failure when using queueless-thread-pool as the pool for a web connector ------------------------------------------------------------------------ Key: WFLY-980 URL: https://issues.jboss.org/browse/WFLY-980 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Server Reporter: Brian Stansberry Assignee: Jason Greene User is reporting a failure when configuring a queueless-thread-pool as the pool for a web connector. The report is for a SIGSEGV but I believe that is just because the native connector is being used; if it weren't this would just show up as a normal java exception. The relevant code in QueuelessExecutor is here: if (executor != null) { executor.execute(task); } else { throw new RejectedExecutionException(); } The exception is thrown because 'executor' is null. We'll need configuration information from the user to understand why that is the case. Here's the user report: SIGSEGV occurs when specify queueless-thread-pool to executor of connector This is a piece of log when the error occurs. 10:13:44,590 ERROR [org.apache.tomcat.util.net.AprEndpoint] (ajp-0.0.0.0-0.0.0.0-8009-Poller) Error allocating socket processor: java.util.concurrent.RejectedExecutionException at org.jboss.threads.QueuelessExecutor.execute(QueuelessExecutor.java:370) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at org.jboss.threads.DelegatingBlockingExecutorService.execute(DelegatingBlockingExecutorService.java:42) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at org.jboss.as.threads.ManagedExecutorService.execute(ManagedExecutorService.java:64) [jboss-as-threads-7.1.0.CR1-redhat-1.jar:7.1.0.CR1-redhat-1] at org.apache.tomcat.util.net.AprEndpoint.processSocket(AprEndpoint.java:1007) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1819) [jbossweb-7.0.7.Final-redhat-1.jar:] at java.lang.Thread.run(Thread.java:636) [:1.6.0_20] 10:13:44,581 ERROR [org.apache.coyote.ajp.AjpAprProtocol] (web-threads - 51) Error reading request, ignored: org.apache.tomcat.jni.Error: Socket operation on non-socket at org.apache.tomcat.jni.Socket.setrbb(Native Method) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:422) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.apache.coyote.ajp.AjpAprProtocol$AjpConnectionHandler.process(AjpAprProtocol.java:480) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:2510) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.jboss.threads.SimpleDirectExecutor.execute(SimpleDirectExecutor.java:33) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at org.jboss.threads.QueuelessExecutor$Worker.run(QueuelessExecutor.java:614) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at java.lang.Thread.run(Thread.java:636) [:1.6.0_20] at org.jboss.threads.JBossThread.run(JBossThread.java:122) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00002aaac0e94a31, pid=29121, tid=1120581952 # # JRE version: 6.0_20-b20 # Java VM: OpenJDK 64-Bit Server VM (19.0-b09 mixed mode linux-amd64 compressed oops) # Derivative: IcedTea6 1.9.8 # Distribution: CentOS release 5.6 (Final), package rhel-1.22.1.9.8.el5_6-x86_64 # Problematic frame: # C [libtcnative-1.so+0x17a31] Java_org_apache_tomcat_jni_Socket_destroy+0x11 # # An error report file with more information is saved as: # /root/jboss-eap-6.0/bin/hs_err_pid29121.log 10:13:44,588 ERROR [org.apache.tomcat.util.net.AprEndpoint] (ajp-0.0.0.0-0.0.0.0-8009-Acceptor) Error allocating socket processor: java.util.concurrent.RejectedExecutionException at org.jboss.threads.QueuelessExecutor.execute(QueuelessExecutor.java:370) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at org.jboss.threads.DelegatingBlockingExecutorService.execute(DelegatingBlockingExecutorService.java:42) [jboss-threads-2.0.0.GA-redhat-1.jar:2.0.0.GA-redhat-1] at org.jboss.as.threads.ManagedExecutorService.execute(ManagedExecutorService.java:64) [jboss-as-threads-7.1.0.CR1-redhat-1.jar:7.1.0.CR1-redhat-1] at org.apache.tomcat.util.net.AprEndpoint.processSocketWithOptions(AprEndpoint.java:982) [jbossweb-7.0.7.Final-redhat-1.jar:] at org.apache.tomcat.util.net.AprEndpoint$Acceptor.run(AprEndpoint.java:1132) [jbossweb-7.0.7.Final-redhat-1.jar:] at java.lang.Thread.run(Thread.java:636) [:1.6.0_20] [thread 1115580736 also had an error] [thread 1115580736 also had an error] # # If you would like to submit a bug report, please include # instructions how to reproduce the bug and visit: # http://icedtea.classpath.org/bugzilla # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. #
